Description
- This application claims priority to U.S. Provisional Patent Application Ser. No. 60/715,537, filed Sep. 9, 2005.
- 1. Field of the Invention
- The present invention relates to optical fibers and, more specifically, to an optical fiber having improved characteristics.
- 2. Description of the Related Art
- An optical fiber is a cylindrical dielectric waveguide, usually made of glass, that transmits light along its axis by the process of total internal reflection. The fiber generally consists of a denser core surrounded by a cladding layer and is made by constructing a large-diameter preform that is pulled to form a long, thin optical fiber. Although optical fibers are used primarily for the transmission of communications, optical fibers have been used as sensors to measure strain, temperature, pressure and other parameters. The light absorption spectra and light intensity dependence of conventional optical fibers, however, limit their utility for such applications.
- It is therefore a principal object and advantage of the present invention to provide an optical fiber having an improved light absorption spectrum.
- It is an additional object and advantage of the present invention to provide an optical fiber having improved light intensity dependence.
- It is a further object and advantage of the present invention to provide an optical fiber that may be used as a sensor.
- It is another object and advantage of the present invention to provide an process for manufacturing improved optical fibers.
- In accordance with the foregoing objects and advantages, the present invention comprises an optical fiber having a thin layer of gold positioned between the core and cladding. The gold layer is vacuum deposited on a rotating clean glass rod which will become the fiber core. The rod is inserted into a tube that will form the cladding of the fiber. The tube is sealed and placed in a hot tin bath inside a stainless steel pressure chamber that is pressurized and heated to collapse the cladding around the gold-coated core, thereby forming a fiber perform that may be pulled to form the gold metal cylinder fiber of the present invention. The fiber may be cleaved at one end and etched to expose a gold cylinder, thereby forming a highly responsive sensor having various uses.

-

FIG. 8 is a schematic of a sensing process according to the present invention. -
FIG. 9 is a schematic of a gold metal fiber sensor system according to the present invention. - Referring now to the drawings, wherein like reference numerals refer to like parts throughout, there is seen in
FIG. 1 anoptical fiber 10 according to the present invention. Fiber 10 comprises aglass core 12, aglass cladding 14, and a layer ofgold 16 disposed betweencore 12 and cladding 14. - Fabrication of
fiber 10 starts with the vacuum deposition of agold film 18 on a rotating 0.5 mmdiameter glass rod 20. Before deposition,glass rod 20 is thoroughly cleaned.Glass rod 20 rotates during the deposition process so that a uniformgold metal film 18 is deposited thereon.Glass rod 20 eventually becomescore 12 offiber 10. The samegold metal film 18 may be deposited on flat glass pieces so that it may be measured. The thickness of thegold metal film 18 onrod 20 is equal to 1/π times the thickness of the deposited film on flat glass pieces. Thus, it is possible to determine the thickness of the depositedgold metal film 18 oncore rod 20. - Coated
glass rod 20 is removed from the vacuum system and inserted into aglass tube 22 having a 1.5 mm inside diameter and a 6.3 mm outside diameter that has been sealed at one end. Tube 22 will eventually form cladding 14 offiber 10. The gold will not be affected by transporting it through the air between the vacuum system andcladding tube 22. Beforecore rod 20 is placed intocladding tube 22,cladding tube 22 is thoroughly cleaned. - A Corning type 7056 glass with a softening point of 702° C. and an index of refraction of 1.487 may be used for
core rod 20 and a Corning type 7052 glass with a softening point of 712° C. and an index of refraction of 1.484 for thecladding tube 22. Alternatively, Corning type 7440 (“Pyrex”) glass with a softening point of 821° C. and an index of refraction of 1.474 may be used for both thecore rod 20 and cladding 22. In the later case,gold film 18 would have to provide some guiding. - After placing coated
core rod 20 intocladding tube 22,cladding tube 22 is evacuated and sealed to form anampoule 24.Ampoule 24 is placed into aboat 26 filled with tin (Sn)solder 28, as seen inFIG. 2 .Boat 26 is placed into a stainlesssteel pressure chamber 30 is then closed and pressurized to about 27 atmospheres (about 400 lbs per square inch) before preheating in a preheat furnace (not shown) to a temperature of 300 degrees Celsius to meltSn solder 28, as seen inFIG. 3 . Ampoule 24 floats in the liquid Sn solder 28, heating it uniformly along its length. - Stainless
steel pressure chamber 30 is then moved into a second furnace (not shown) set to a temperature of 630 degrees Celsius (for the lower temperature type 7052 or 7056 glass). Whenampoule 24 reaches a temperature of 620 degrees Celsius,cladding tube 22 collapses onto thecore rod 20, trapping thethin gold film 18 between them, as seen inFIG. 4 . Collapsedampoule 24 should have a diameter of 6.139 mm. Note that the collapsing occurs at a temperature well below the softening temperature of the glass. While the collapsing process is not visible whileampoule 24 is inpressure chamber 30, theory suggests that the collapsing process occurs very rapidly once the glass has reached the proper temperature because, at that temperature, the glass has the proper viscosity for collapse. - The collapsing of
ampoule 24 forms a fiber perform 36.Pressure chamber 30 containing perform 36 is slowly returned to preheat furnace 32. This movement should take 4 to 6 hours, thereby annealing perform 36 in the process. The glass cools while floating in the liquid Sn. This assures that perform 36 remains straight while the glass hardens. -
Preform 36 is preferably about 20 cm long at this point. Next, glass handles (not shown) that are each about 30 cm long are attached to each end ofperform 36.Preform 36 is mounted in afiber drawing tower 40, as seen inFIG. 9 .Fiber 10 is then drawn from perform 36 in a fiber pulling tower, as seen inFIG. 5 . A force of 200 grams is applied tofiber 10 during the pulling process.Fiber 10 is pulled at a temperature of 630 degrees Celsius for the type 7052 or 7056 glass with the lower softening point. At this temperature, the glass has a higher viscosity than the gold. Thus, the gold is extruded from a thickness of 0.1 μm inpreform 36 to a thickness of 2.06 nm infiber 10 by the surrounding glass. If the viscosity of the glass is less than the viscosity of the gold, the gold will tear during the fiber pulling process. The 0.5 mm diameter core of the preform is drawn to a 10.03 μm core infiber 10 and the 6.139 mm outside diameter ofpreform 36 becomes the 126.4 μm outside diameter offiber 10. -
Fiber 10 according to the present invention may be used as a sensor. Since one can etch glass without etching the gold metal layer positioned betweencore 12 andcladding 14, it is possible to construct afiber 10 with a protruding very thinhollow gold cylinder 42, as seen inFIG. 6 . These devices are made by first fabricatingfiber 10 with a gold layer betweencore 12 andcladding 14, as explained above. An end offiber 10 is then cleaved to obtain a flat uniform surface. Next, the cleaved end offiber 10 is submerged in hydrofluoric acid. The acid will etch away some of the glass, leaving a protrudinghollow gold cylinder 42. - An alternate arrangement is to fabricate a
fiber 10 with two or more thin goldcylindrical arc sections 44 at the core cladding boundary. One end offiber 10 is then cleaved to obtain a flat uniform surface. Next, the cleaved end offiber 10 is submerged in hydrofluoric acid. The acid will etch away some of the glass leaving protruding goldcylindrical arc sections 44, as seen inFIG. 7 . - The protruding
gold cylinder 42 orcylindrical arc sections 44 offiber 10 may be used as strain or fluid flow sensors. Since the very thin sections are easily deflected these can be very sensitive detectors. These devices can be also used as pressure sensors. They will sense any pressure induced strain in a material in which they are imbedded. - The lowest order modes propagate through
gold layer 16 and the glass immediately next togold layer 16. Thus, any light reflected from the end with the protrudinggold structures gold sections fiber 10. Some of the light will be reflected from the fiber end containing thegold structures gold film 16 it will carry back information about the material placed ongold structures - The molecules and the protruding
gold structures fiber 10 by coating aglass slide 48 with a thin film of suspension containing the molecules to be tested. The protrudinggold structures fiber 10 are dipped carefully into the suspension film onglass slide 48, as seen inFIG. 8 . Before measuring,fiber 10 is pulled away from the glass slide, thereby depositing a small amount of the suspension with the molecules on thegold structures - A
sensor system 50 using agold metal fiber 10 according to the present invention is seen inFIG. 9 . Light from alaser 52 propagates alongfiber 54 to a sensor 56 (i.e.,fiber 10 having extending cylindrical gold cylinder or cylindrical sections) through adirectional coupler 58. The reflected light fromsensor 56 is directed bydirectional coupler 58 to adetector 60. If the distance betweendirectional coupler 58 andsensor 56 is long, a standard single mode fiber may be used between a short piece offiber 10 anddirectional coupler 58.
